To (0U whmn it may concern.-

Be it known that i, HENRY T. BRAGG, a

citizen of the U nitcd States, and resident of- Yonkers, in the county of i festchester and State of New York, have invented new and useful improvements in Tires, of which the folloviing is a specification. i

The object of my invention is to provide certain improvements in tires whereby the resiliency of the tire will be niateriellyirn creased by the use. of u knitted fabric, the sides of the tire at the some time being reinforced by knitting the fabric more closely at the side of the tire then along the tread portion thereof.

A still further object is to provide a tire of the clencher type in which the above construction is provided, the clenohes of the tire" also having incorporated therein the more closely-knitted portions of the fabric.

It has been found in actual practice that the tendency of pneumatic tires to break along the sides thereof is extremely great whilein use. i.

The chief object of this present invention is to provide on elastic fabric for tires which Will prevent the breaking of the tire along the sides thereof, the fabric at the some ti 1e heing capable of being knitted su'liiciently close elong the sides of the tire. to properly strengthen and reinforce the some, the portion of the fabric along the tread of the tire being loosely knitted, so 33 to give great resiliency at this point. I

A still further object is to provide it tireshoe in which a flat-knitted fabric may be used, thus absolutely preventing any tendency of the edges of the fabric to become weakened as would be the case if a tubularknit fabric was longitudinally severed and then incorporated in the shoe.

A practical embodiment of my. invention is represented in the accompanying drawings, in which Figure 1 is a transversesection through a pneumatictire of the clencher type, showing it applied to a rim; and Fi 2 is a. detail view of a portion of the knitted fabric, showing the some as bein provided with a loosely-knit ted trend portion and closely-knitted side portions.

The rim is denoted by 1, the inner air-tube of the tire by 2, and the tire-shoe by The knitted fabric comprises a loosely-knitted tread portion 4 and closely knitted side portions 5 end 6. This fa brie is knitted dot and is incorporated in the tires hoe, the closelyknitted portions of the fabric being of sutiicient length to not only reinforce the sides of the tire-shoe, but also to around and reinforce the clenches and S ofthe shoe;

The looselyf-knittcd tread portion of the fabric will perinit a. free fielding of the tread portion of he tire, and the reinforced side portions, Which are formed integral with the knitted fabric, serve to properly strengthen the sides of the tire at the points Where there is it great tendency for the tires to break when in use.

By the use of a knitted fabric constructed as herein set forth i am enabled to incorporote into the tire aiewer number of layers of t bric their hes heretofore been possible in this art and attire some time obtain the greatest resiliency for the tire, because of the natural elesticity of the knitted fabric, and also obtain greater strength than has heretofore been possible with a. predetermined amount of fabric.

What 1 claim is 1. A tire having a knitted fabric incorporated therein, said knittedfobrio having knitted reinforced portions integral therewith along the sides of the tire.

2. A tire-shoe of the clsnchertype having a knitted fabric incorporated therein, the said knitted fabric liiavingknitted reinforced portions integral therewith along the sides of the shoe.

3. Atire-shoe of the clenoher type having a flat-knitted fabric incorporated therein, the said flat-knitted fabric having knitted reinforced portions integral therewith along the sides of the shoe.

4. Atire having a knitted fabric incorporated therein provided With a loosely-knitted tread portion and closely-knitted side portions.

5. Atireshoe of the clencher type havings knitted fabric incorporated therein provided with a. loosely-knitted tread portion and closely-knitted side portions. I

6. Atire-shoe of the clencher type having a fiat-knitted fabric incorporated therein pro vided with o loosely-knitted tread portion and closely-knitted side portions.

7. A tire having a single layer-of knitted fabric incorporated therein, :1 ertain portion of the fabric being loosely knitted and other portions beingclosely knit ed.

8. A. tireshoe of the clencher type having a single layer of knitted fabric incorporated single layer of flat knitted fabric incorporated sss,sos
